Though its capacity is on the smaller side and it doesn’t have as many features as other air purifiers on this list, it’s hard to beat the price. Aesthetically, it wouldn’t be out of place on your nightstand with its white or black case and sleek design.

While this air purifier was designed for use in the bedroom (its fan is ultra quiet and it features an optional soft blue night light with two brightness settings), it’s quite portable and can be moved from room to room if needed. And three fan settings let you control the speed and volume of the purifier. Instead it features a three-stage filtration system that includes a pre-filter, a HEPA filter and an activated carbon filter. It’s an excellent, inexpensive option that eschews technology like UV and ionization more commonly found in this price range. Small enough to fit on your desk and designed to filter up to about 129 square feet, this compact Levoit model is equipped with a HEPA filter that removes 99.97% of dust, pollen, smoke, odor, mold spores and pet dander. HEPA filter: Yes | Filter maintenance: Replaceable | Dimensions: 8 x 8 x 12.5 inches | Coverage area: 129 sq.
